Default 10 Megohm resistors

Hi Does anyone have some 10 Meg-ohm 1/2 watt carbon resistors that they could sell me, please? I am restoring some 1950's radios and the grid load resistors for the triode section of EABC80 valves tend to go over their specified values.
Thanks
Mike

I have a large number of these ISKRA carbon-film types. Body size is 4mm dia. x 10mm long from their UPM075 range so believed to be 0.75W max rating.
How many are you looking for ?

Hi Andy.
Many thanks.
About 10 will do. How much do you want for them, please?
It is just to replace grid resistors. My German Blaupunkt "Virginia" radio (EABC80 grid of triode) seems to have gone up in value to about 13 meg ohm. I thought those red metal resistors were usually very stable.
Many thanks
Mike

Doubt that it will make any difference if only 3 meg high. Some sets had 20% resistors anyway in this position so it's not very critical.

Agreed, I've never changed one of these resistors.

Hi Mike,
If you only need ~10 then PM me with your address and I'll send them in the post.
In the spirit of Christmas you can have them free of charge.

Cheers,
Andy
